Cold Hardy Citrus / Re: 28 F, -2.2 C
« on: November 17, 2021, 09:11:03 PM »
I donít take a chance with fruit on tree. I cover and try to avoid freezing the fruit. My grapefruit and meiwa fruit have to go the entire winter on the tree before ripe. Itís distressing to cut a beautiful red grapefruit in half and see it a dry husk inside. Too much effort put in to not get a crop.

Temperate Fruit Discussion / Native crabapple as rootstock
« on: November 15, 2021, 09:11:51 AM »
Does anyone know if native crabapple such as malas coronaria or angustifolia can make good rootstocks for modern apple cultivars such as McIntosh or red delicious? Iím good with cleft graft citrus but havenít tried apples yet.

Citrus General Discussion / Re: Is this HLB?
« on: November 03, 2021, 08:44:17 PM »
Usually HLB yellow blotches will be asymmetrical with right side of leaf looking different than left. Yours look pretty symmetrical to me. HLB will make lopsided fruit with yellow discoloration too. You want to keep your nutrition up in an HLB region. Lack of nutrition with yellowing of leaves will make tree more susceptible to HLB.

Since youíre in south central FL which is greeningís favorite place to thrive, send pics to your local horticultural extension agent for a diagnosis. You should be able to send it in an email. Best of luck.

Cold Hardy Citrus / Re: Collins Poncirus processing
« on: November 01, 2021, 09:53:39 AM »
My poncirus fruits are large and juice filled like yours. I squeeze the juice out, boil it, settle out the bitter oils in fridge overnight, siphon off the juice leaving oil behind, and  put juice up in freezer in cup-size containers, and take out one container a week or so and mix it with water in a orange juice carafe and sweeten to taste with stevia. It makes a strong lemonade that I drink every morning out of a small orange juice glass.

Could it be a grapefruit deformed by mites?

What do they cover them with? Bed sheets? Frost cloth?

Citrus General Discussion / Re: Should we be bare rooting trees?
« on: October 18, 2021, 07:58:00 PM »
I repotted all my citrus in 50:50 Turface/ garden soil this year and removed all the previous potting soil, lost a few minor roots in process, but within a week or two, everything started pushing new growth, big Saint Teresa bloomed and fruited for the first time. Done great. Iíve cultivated bonsai trees in the past, not citrus species, but other species such as crabapple and dwarf pomegranate, azalea, wisteria, etc, and of course had to severely root prune and top prune proportionately of course, and they all did well and were potted in bonsai soil which resembles the 50:50 Turface blend. Amazing how plants can recover from pruning with appropriate aftercare. Osmacote mixed in with my Turface by the way.

Cold Hardy Citrus / Re: Anyone growing Croxton Grapefruit?
« on: October 15, 2021, 09:39:12 PM »
I donít prune the Croxton. Itís a little wider than tall now. The grapefruit of both varieties are not ripe until the following spring but stay on tree well into the next fall. Most of my trees have outgrown the pvc pipe dome method. When they do, I make a wood frame that is easily taken down in spring or can be left up all year. <br /><br /><br /><br /><br /><br /><br />post image online<br />

This is my Croxton and Rio Star fruit and photos of the Croxton which is sprawling and bush like on flying dragon rootstock covered by pvc pipe frame and plastic sheeting in winter.

Iíve been growing mine on flying dragon since 2013 or so. I cover mine each winter as needed with 4 mil plastic, 32 gallon water barrel, space heater 250 watt regulated by thermo cube. I get 8 or large fruit off of it each year and they are very sweet and juicy for a grapefruit. However, although mine have a pink blush on the rind, the inside of the fruit is yellow. I got mine from Ben Salley at Simply Citrus in Columbia SC. He grafted it from the original Croxton tree. I think mine doesnít turn pink inside because it doesnít get very warm here at 3,000 ft elevation in summer. Similarly, my Rio Star grapefruit turns pink but not a full red. My Croxton has performed well each winter without die back using the method described, even one year when it didnít get above freezing for the whole month of January.  I just make sure to uncover it when temps get above freezing to keep it cold and dormant. I actually like the taste and texture of it better than the Rio Star.

Such a tragedy.

It depends on what state youíre in. There are citrus quarantines in most citrus producing states. If you can get citrus from SC , McKenzie Farms in Scranton, SC will have cold hardy varieties. He should have Changsha and Ichang lemon and some citranges. I have some Changsha and Benton and Meiwa saplings and some Citradia on poncirus rootstock. Iím in NC with no quarantine issues. You can try Madison Citrus online but most of their citrus youíre going to have to protect in winter except they have rootstocks that are fully hardy for zone 7.

Citrus General Discussion / Re: Trying A New Growth Medium
« on: September 23, 2021, 09:21:05 PM »
My trees are doing very well in the 50:50 Turface:Miracle Grow Garden Soil. My Saint Teresa bloomed for the first time in two years after the repotting from Miracle Grow Citrus soil to the 50:50 Turface. My other potted citrus have put on a lot of growth this summer since the transition from cheap potting soil as well, especially the meiwa kumquat seedlings.

Oops! Sorry. I just reread the title of your post, ďrepotting.Ē Geeze. Yeah. Put it in better soil. No worries.

Incubator01, are you planting it in ground or just repotting in better potting media? If itís staying in a pot and being protected from winter freeze, it doesnít matter when you repot it. I broke the rules one year and planted a Rio Red grapefruit and an Owari in ground after I purchased them in mid November but I protected them from severe freezing over winter with my cold frames and space heater method.

If you want a citrus comparable to south central FL quality that you can grow in ground in zone 7 in southeastern USA, you will probably need to protect it some during winter. Main idea is keep it cold and dormant but try to avoid severe low temps and prolonged times spent below freezing. Protect fruit still on tree from freezing. Focus on early fruiting satsumas that harvest before your first freeze if possible. I have to protect all of my citrus here and most still have fruit on them through December and even into next spring. My good quality citrus are Owari satsuma, Kimbrough satsumas, Rio Red grapefruit, Croxton grapefruit, meiwa kumquat, Ichang lemon. If you want moderate quality fruit that you can possibly get away without protection there, I would try Ichang lemon, Changsha mandarin, Benton citrange, Thomasville citrangequat.

Cold Hardy Citrus / Citramot?
« on: September 13, 2021, 09:39:54 PM »
I was just researching bergamot and noticed that according to the ucr citrus variety collection site that it is mostly monoembryonic. I think that means if it makes seeds they should be single and from sexual reproduction and therefore seedlings should not be true to type, rather be hybrids. I canít find reference to a poncirus and bergamot hybrid, that I presume could be called a ďcitramot.Ē  My bergamot tree has bloomed repeatedly this year, so I am tempted to try pollination with PT next spring and see what happens. I look forward to everyoneís comments.

Thanks, Ilya11

24
Again, are we implying that the poncirus genes in Sundragon are what gives it HLB protection?

25
Is poncirus supposed to be tolerant of HLB?
